Självklart finns stöd för SpeedStep/Frequency scaling. Wikipedia:
Samma med AMDs motsvarighet.
Funkar finfint. Kör det på servern för att spara ström:

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 160 us.
hardware limits: 1.60 GHz - 3.07 GHz
available frequency steps: 3.07 GHz, 2.13 GHz, 1.60 GHz
available cpufreq governors: userspace, powersave, ondemand, performance
current policy: frequency should be within 1.60 GHz and 3.07 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.60 GHz.
cpufreq stats: 3.07 GHz:0.10%, 2.13 GHz:0.02%, 1.60 GHz:99.88% (969)

För Gnome/KDE finns nån fin sak till panelen för att ändra frekvens/governor (svensk översättning på det!?)
